JOHN STUART DANIELS AND FREDERIC LONEL DANIELS, OF STROUD, ENGLAND.

GAS-PRODUCER.

SPECIFICATION forming part of Letters Patent No. 738,004, dated September 1, 1903. Application filed April 6, 1903. Serial No. 151,327. (No modelJ To @ZZ whom t may concern.,-

Beit known that we, JOHN STUART DANrELs and FREDERIC LIONEL DAN1ELs,both of Lightpill Iron lVorks, Stroud, in the county of Gloucester, England, have invented certain new and useful Improvements' in Gas-Producers, (for which We have made application forLetters Patent in Great Britain, No. 7,613, dated March 29, 1902,) of which the following is a specification.

rlhis invention relates to improvements in connection With gas-prod ucers that are for use with bituminous coal or other fuel containing volatile matters, the object being to improve the means for collecting and utilizing the distilled and condensable gases from the upper portion of the producer and to improve the method of constructing and arranging the {irebars and other fittings for use upon such producers-a Referring to the accompanying drawings, Figure l is a central vertical section on line B B of Fig. 3. Fig. 2 is a similar view taken on line A A of Fig. 3. Fig. 3 is a horizontal section on line C C of Fig. l. Fig. 4t is a ccntral vertical section of a modified form. Fig. 4 is a similar-view at right angles to Fig. 4. Fig. 5 is a central vertical section of a still further modification, and Fig. 5 is a section at right angles to Fig. 5.

In carrying our invention into eifect in one convenient manner, as illustrated in Figsl to 3, We provide a casing or inclosing shell a, of metal or other suitable materiahwithin which we build up our fire-brick or other like material lining b. At the upper end of the casing We arrange a feeding-hopper b with a valve or other covering and protecting device b2, and we cause the feeding-hopper tube or inner branchfto project below the upper end g of the interior chamber e, so as to thereby form an annular collecting head or passage, from which the distilled gases and vapors may be drawn or allowed to escape by means of an opening or openings h', leading thereto.

We collect the distilled gases and other products from the upper portion of the producer by means of a branch opening h', which leads into a conduit passage or pipe 71 that may be carried down Within the material forming the lining b of the producer or by means of an independent exhaust pipe or pipes. The lower end of this collecting conduit or pipe h We join to a feeder branch 7o, which delivers the distillates and gases to the lower portion of the fire-grate within the zone of combustion. We

make the delivering conduit or pipe 7c, pref-' erably, as a central support, against which the tire-bars Z can abut, forming such hollow central support With slots or openings,through which the distillates can be delivered and through which the steam for decomposition in the interior of the gas-producer can also pass.

We introduce steam through a nozzlej for the creation of an induced draft in the distillate pipe or conduit 7c, in any convenient position to suit the form of conduit and connections that may be employed. We make our conduits and connecplacing such nozzle tions with outer flanges or doors, so that cleaning can be easily accomplished by the removal of such covers.

Within the interior of the producer we some'- times arrange our improved projecting ringlike collector d for leading to the gas-outlet passage. We, however, make our collector d in various forms to suit the size of producer that is to be constructed and the connections that are to be used with the same. We arrange our fire-grate in the form of bars l, which we carry on central spindles m or bearers that are capable of being rocked, so that the bars are made to move to a determined extent by the rocking of the spindles, and thus to break up thefuel supported thereon and to obviate the clinkering, which would otherwise result. The spindlesm are provided with exterior hand-leveren. The levers are adapted to move between removable and adjustable stops, (not shown,) which limit the amount of rocking that can be given to the grate and which can be removed altogether when desired to allow the grate to be turned through a considerable angle when the producer is open for cleaning. We prefer to make the rocking bars Z to intermesh on their inner ends with projecting bars q, formed upon the bearer members k, and we make the ends s of the rocking bars of such a form that they do not move entirely away from the lower end of such fixed bars. By this provision we prevent the entrance of small pieces of clinker or coal between the fixed bars and the rocking-bars.

We sometimes employ supplementary or auxillary grate-bars within our furnacegrate, and we make these auxiliary bars as fixtures or to rock, as may be desired, preferably mounting them in such a position, as shown in Fig. l, that an angular bed-like support is formed for the fuel at its base.

These auxiliary bars serve to hold the fire clear of the Water ash-pit p and to form an additional support for the side surface of the fuel at its base. Air is supplied beneath the grate by a pipe t.

At the lower end of our gas-producer casing we provide an ash-pit p, which we ll to any desired level with water, making such ash-pit preferably of greater dimensions than the exterior portion of the casing of our producer.

When constructing another form of our improved gas-producer, as illustrated in Fig. 4, we arrange our rocking bars at the lower sides of a wedge-like base c of the producer-chamber e, (which chamber is of rectangular crosssection,) and we make such bars to intermesh at their ends with fixed ribs or bars q', formed upon the bearer-supports 1', and similar ribs q2 upon the -sides of the open passage or ash -pit Wasteoutlet r between the inclined bars. We cause these bars to rock on either side, so as to obtain a complete disturbance of the fuel upon the bars when in operation. In this form we have omitted the annular collector cl, providing simply a single collecting-outlet CZ at one side. We also provide a steaminjecting pipe j in the pipe or conduit h. In this forin it will be seen that the distillates are passed through conduit h into the central hollow perforated conduit lo, the fire-bars being disposed on each side thereof.

By another modification of our improved gas-producer, as illustrated in Fig. 5, we provide for a treatment of fuel in small and medium quantities by mounting the rocking firebars Z2 in an inclined manner upon ashaft m2 on one side of the base of the hearth, making the conduit-passage 7?, for the distillates to enter the central bearer-like member la', on each side of which the bars are mounted or supported, and we arrange projecting bars Q3 to intermesh with the openings of our rocking bars in the manner and for the purpose hereinbefor'e described. In this form of construction of gas-producer we deliver the air bya conduit z5 to the under side of the grate, through which it passes.

We provide for the ash removal by forming an open channel x at one side of the base of the grate, which channel leads to the trough or water-chamber p2, arranged beneath the base of the fire-grate, such chamber being made of any desired form to suit the mountings and ttings in connection with the casing to which it is to be applied.

Ve do not limit the application of our improved arrangement of rocking bars and the improved method for collecting and feeding the distillates and steam to the hre-grate to any particular form of casing or any specia arrangement of water-trough or other fittings to be used in connection With such gas-producers; but we modifyV the arrangement and the construction of such members to suit the type and size ofgas-producer that is to be constructed andthe fittings to be employed therewith.

Having thus described ourinvention, what We claim as new, and desire to secure by Letters Patent, is

1. In a gas-producer the combination with the prod ricer-chamber, of a hollow perforated conduit having communication with the upper part'of the producer and arranged to support fuel and to deliver distillates thereto,and inclined pivoted fire-bars on each side of said conduit, substantially as described.
